Interesting theory. Idk how it's done but to me it looks sort of half swirled/ half splattered. I'd like to see what the JS looks like with the lights on-- EDIT ohh didn't see pic 3 at first...That is wild! Idk about a dip... It looks like water. As if it is brushed on watered down UV illuminated paint. Then the water evaporates or something. It's definitely different.
